我已经成功地将我的UITableViewCell左右滑动以将单元格标记为已读或删除它(有点像Reeder应用程序如何执行)但现在它不允许我简单地点击它。我如何允许它被点击?
我使用this article作为概念的结构,因此可以获得更多信息。
我按如下方式实现了滑动:
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
_firstTouchPoint = [[touches anyObject] locationInView:self];
}
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
CGPoint touchPoint = [[touches anyObject] locationInView:self];
// Holds the value of how far away from the first touch the finger has moved
CGFloat xPos;
// If the first touch point is left of the current point, it means the user is moving their finger right and the cell must move right
if (_firstTouchPoint.x < touchPoint.x) {
xPos = touchPoint.x - _firstTouchPoint.x;
if (xPos <= 0) {
xPos = 0;
}
}
else {
xPos = -(_firstTouchPoint.x - touchPoint.x);
if (xPos >= 0) {
xPos = 0;
}
}
// Change our cellFront's origin to the xPos we defined
CGRect frame = self.cellFront.frame;
frame.origin = CGPointMake(xPos, 0);
self.cellFront.frame = frame;
}
- (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event {
[self springBack];
}
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
[self springBack];
}
- (void)springBack {
CGFloat cellXPositionBeforeSpringBack = self.cellFront.frame.origin.x;
CGRect frame = self.cellFront.frame;
frame.origin = CGPointMake(0, 0);
[UIView animateWithDuration:0.1 delay:0.0 options:UIViewAnimationOptionCurveEaseOut animations:^{
self.cellFront.frame = frame;
} completion:^(BOOL finished) {
}];
if (cellXPositionBeforeSpringBack >= 80 || cellXPositionBeforeSpringBack <= -80) {
NSLog(@"YA");
}
}
当我点击它时,没有任何反应。

只需使用UIPanGestureRecognizer。
触摸开始的方法是如此古老。 使用平移手势,您不会丢失手机上的触摸事件。答案 1 :(得分:0)
最容易解决的,实际上是建立自己的左右滑动手势。 构建它之后,只需将此手势添加到视图中,并添加轻击手势。
如果您通过实施'shouldRecognizeSimultaneouslyWithGestureRecognizer'方法同时允许两个手势(点击手势和滑动手势)同时生效,iOS将非常轻松地为您处理。
